Cannot Open PowerPoint 4.0 Files Using PowerPoint 2013
I have many files created with PowerPoint 4.0 that cannot be opened with PowerPoint 2013. This appears to be a known issue. When trying to open the file, receive PowerPoint message: "PowerPoint can't open this type of file (...\filname.ppt)."
Details of the message: "The selected file does not appear to be a valid Microsoft PowerPoint file. It might be a file created by a different program.
Try double-clicking the file in Windows Explorer to see if another program will open it. If PowerPoint opens again when you double-click the file in Windows Explorer, it is possible that the file is not a PowerPoint file but that its extension was renamed to be that of a registered PowerPoint file type (such as .ppt, .pptx, .pps, .ppsx, .pptx, .pot, or .potx) but the file is not a PowerPoint file.
To determine which program can open the file, try any of the following:
Contact the original author (if known) to find out which program was used to create this file. Then rename the file with the correct extension so that it can be opened by that program.
Try opening the file in other programs.
If you, or someone you know, are very knowledgeable about software, examine the file header in a text editor to determine which program can read the file.
Another possibility is that the file was damaged during transfer from another computer. Try transferring the file again.
The file might have become corrupted. If you have a backup copy of the file, use it. It is not possible repair a corrupted"
I found an online tool (ZAMZAR), but cannot use it (work security issues). Other than trying to find an older o/s (XP?) and PowerPoint, any other possibilities?

Robert: Failed to convert. Guessing that's due to running this on a Windows 10, 64-bit workstation?
Ramin: Can't use ZAMZAR. Trying to locate workstation with older software.
